Abstract

PCT No. PCT/FI94/00078 Sec. 371 Date Feb. 15, 1996 Sec. 102(e) Date Feb. 15, 1996 PCT Filed Mar. 3, 1994 PCT Pub. No. WO94/20666 PCT Pub. Date Sep. 15, 1994An enzymatic process for treating coarse pulp with an enzyme having cellobiohydrolase activity to reduce the specific energy requirements of the pulp and improve the properties of the pulp. Cellobiohydrolase enzymes isolated from the species Trichoderma, Aspergillus, Phanerochaete, Penicillium, Streptomyces, Humicola or Bacillus can be used.
